It's tough when you create something like a song, a musical work, a play, or a book (or anything else for that matter). You have an experience that no one else who ever sees or hears the work will have ... because you created it.
But you, in turn, have no idea how other people see it. At best, you can try to be objective and pretend to stand in their shoes ... but you know exactly where every creative decision came from, whether based on reality, a personal experience, or imagination. So your intentions can be different from an audience's perception ... or even an actor or director's perception.
Albee wrote a good play. Alan Schneider and Mike Nichols made it into a great play and classic material. It may not have been the author's intent ... just like William Inge wanted a different ending for Picnic (discussed in another thread) ... but ultimately what worked best won out.
It's important to remember that theatre is a collaborative art form. Sondheim always talks about that. His intentions for Sweeney Todd on stage were very different from Hal Prince's, but the two together created a masterpiece.
As much as I admire Sondheim and other writers and authors .... and as much as I respect that theatre is considered a writer's medium (where film is a director's medium) ... none of them did it alone. Far from it.
